Hi all,
I recently acquired a Kill-a-Watt power meter which
tells me how much electricity is being used by any
125-VAC appliance I desire to test.
I was amazed to see that my new Toshiba laptop,
which uses a Celeron M processor 1.5 GHz and has a big
15 inch display, is very energy efficient indeed
especially when compared to my previous Toshiba.
Running simple programs like a word processor
and web browser, it averages about 20 watts only.
That's when I have the wireless card active also.
When I'm running it at full tilt with the CPU
load at 100% and the hard drive being accessed
and wireless turned on, it only uses 30 watts.
This is a big savings over my last Toshiba, which
used 60 watts, which was almost an identical
computer but had a Celeron 2.4 GHz.
I suspect the CPU is the major factor.
The Celeron M is supposed to be more power efficient
than the Celeron, plus it is slower. Although
Intel says its power savings circuitry is inferior
to that of a Pentium M.
